ELECTRIC-DISTRIBUTION SYSTEM FOR RAILWAYS.

SPECIFICATION forming partof Letters Patent No. 496,533, dated May 2, 1893.

Application filed May 27, 1891.

To all whom it may concern.-

Be it known that I, NELSON W. PERRY, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Systems of Electric Distribution and in Mechanism Therefor, of which the following is a specification.

My invention relates more particularly to methods of electric distribution for moving translating devices operated by the multiple are system. In the systems of electric distribution for moving translating devices nowin use the liability to leakage and the danger incident to the use of bare working conductors has been a serious drawback both in overhead and underground systems but especially in the latter. I

It is the object of my invention to provide a system of distribution in which the danger and the liability of leakage from the working wires will be reduced to the minimum and the invention consists in the system and the mechanism hereinafter described.

In the drawings: Figures 1, 2 and 3 are diagrammatic views showing my invention applied to an electric railway operated by a single working conductor, or trolley wire, the motor being shown in difierent positions in each of the figures. Fig. 4 is a like view showing my invention applied to a double trolley line. Fig. 5 is a detail of a portion of a trip switch.

A is the outgoing or positive feed wire and A (Fig. 4) a return or negative feed wire employed in roads operated on the double trolley system.

B, B and B represent sections of the working conductor, each section lapping but normally insulated from the adjacent sections.

B, B and B (Fig. 4) represent sections of a second working conductor used in the double trolley system.

The feed wire A is connected with section B of the working conductor by branch feed wires a c and c b, normally disconnected, but adapted to be connected by a switch, or circuit breaker, O, with section B by wires a o and o 1) adapted to be connected by a switch 0, &c.

D, D are supplemental conductors adja- Serial No. 394,259- (No model.)

cent to the lapping portions of the working conductor but normally insulated therefrom. D is connected with D by a wire d cZ',D with D by a Wire d (1 &c.

E E are solenoid magnets connected respectively with the wires d d, 01 d &c., by wires 6 d, e d, &c. The armatures e of these magnets carry hook shaped extensions 6', preferably pivotally attached thereto and adapted to take about levers F. The levers F are fulcrumed'atfand provided near the fulcrum point with V-shaped lugs or projectionsf'. They are also provided with weights f adapted to bring the center of gravity of the lever above the point of support.

- The levers are adapted to actuate the circuit breaking devices O O, &c., in the connections a c c b, &c., between the main conveyer and the sections of the working conductor I have illustrated these circuit breaking devices as consisting of yokes or forks O O, &c., adapted to take'into pairs of mercury cups 0 c, c c, (950., one member of each pair being mounted at the adjacent ends of the wires a c and c b, a c, 0' 19 &c., and a space being left between the cups. The solenoids E E are connected with the return. In the single trolley system the ground is used for the return and the connection from the solenoids is by wires g, g, g &c. When the double trolley system is used, the return wire, A, is connected with they negative trolley wire (as shown in Fig. 4) by wires ac and c I), normally disconnected by a switch or circuit breaker 0 It will be understood that the return wire is connected in the same manner with each section of the trolley wire. The circuit breaker C is preferably actuated by the same magnet which actuates its companion circuitbreakerGand for that purpose thelever F carries a bar f to which are attached the circuit breaker O and 0 In the double trolley system the return being metallic the solenoids E, E, &c., are connected with the re turn wire by a wire 6 a instead of with the ground as in the single trolley system.

In Fig. 1 the motor M is represented as in electrical connection with one section of the working conductor of a single trolley line. In Fig. 2 the motor is represented as approaching another section of the working conductor,

the switch in the branch feed wire which applies current to the section about to be reached having been closed.

In Fig. 3 the motor is represented as in electrical connection with the lapping portion of two adjacent sections of the working conductor, the circuit through the branch feed wire which supplies current to the first of the two having been broken. The operation when the motor is in electrical connection with a section of the working conductor and the switch wire which supplies that section closed requires no explanation. The switch in the branch feed wire supporting the next succeeding section should be open. When the trolley, or other current gathering device, contacts with supplemental cond uctor D a current is established through d (1 e (l, magnet E and the ground connection 9. This current vitalizes the magnet E and actuates its armature lifting the free end of the lever F and lowering the fork G into the mercury cups 0' thereby making electrical connection between the main feed wire A and section B of the working conductor. As the motor proceeds the trolley contacts with the supplemental conductor D and a current is established through d d, e (Z magnet E and the ground connection g. This current vitalizes magnet E and actuates its armature thereby reversing the position of lever F and breaking the connection in the branch feed wire a c, c b. This cuts section B of the working conductor out of circuit. As soon as the trolley passes from its contact with one of the supplemental conductors the current through the magnet is broken and thearmature drops thereby lowering the lever-actuating book but, the center of gravity of the lever being above its fulcrum, the lever will retain its position until positively actuated. When the lever is tilted the point of its V-shaped projection will extend beyond the normal position of the lever-actuating hook and when the latter drops it always assumes a position under the opposite face of the V-shaped projection from that upon which it last acted. The result. is that, each time a magnet is vitalized, the position of the lever which it controls is reversed and the lever retains its position until the magnet is again vitalized. The supplemental wires are so arranged that as the motor approaches a lap between sections of the working conductor the supplemental conductor, connecting with the switch controlling the section ahead, is first embraced, then the working conductor of the succeedingsection, then, and before passing from either of the other three wires, the supplemental conductor connecting with the switch controlling the section the car is leaving.
